Acoustic Security & Sonar Systems
Acoustic defender, air sonar and sound localization systems for perimeter protection, gunshot detection, intrusion awareness and critical infrastructure security.
Security products built around sound and vibration.
HERTZINNO acoustic security products support buried perimeter detection, air acoustic localization and rapid deployment monitoring for safety, patrol and infrastructure protection scenarios.

- Output: Acoustic direction and event alarm
Three acoustic security layers for different environments.
Underground vibration sensing, air acoustic localization and AI acoustic fingerprinting work together to detect events that cameras may miss.
Underground Defense: HZ-DA-200
HZ-DA-200 is designed for buried deployment along borders, perimeters and restricted areas. It detects ground-borne vibration patterns such as footsteps, vehicles and intrusion activity, while remaining hidden from view and less affected by darkness, fog or surface visibility.
- Buried DeploymentHidden sensing nodes reduce visual exposure and tampering risk.
- Outdoor ProtectionIP68 enclosure supports long-term field installation.
- Event FilteringAlgorithms help reduce false alarms from environmental noise.
- Wireless NetworkLoRaWAN supports long-distance node communication.
Air Acoustic Localization: HZ-SN-16
HZ-SN-16 uses a multi-channel microphone array to determine the direction of high-energy acoustic events such as gunshots, explosions and impact sounds. When integrated with video surveillance, the system can help guide cameras toward the event source for faster confirmation.
- Sound DirectionOutputs acoustic direction and elevation for event localization.
- CCTV LinkageCan support camera steering or visual verification workflows.
- Event ClassificationHelps distinguish key acoustic events from background noise.
- Urban & Site SecuritySuitable for facilities, campuses and protected areas.
Powered by Acoustic Fingerprinting
HERTZINNO acoustic systems analyze waveform, frequency and timing features to distinguish target events from background noise.
Waveform Analysis
Analyzes transient event features such as attack, decay and acoustic energy profile.
Event Classification
Models help separate target sounds from wind, rain, vehicles and environmental noise.
TDOA Localization
Time difference of arrival helps calculate acoustic source direction using microphone arrays.
Where acoustic security systems are used
Acoustic systems provide an additional sensing layer for environments where visual monitoring is limited, delayed or incomplete.
Border & Perimeter Security
Buried acoustic defender nodes detect footsteps, vehicles and intrusion activity along protected routes.
Critical Infrastructure
Monitor restricted energy assets, utility sites, storage zones and infrastructure perimeters.
Urban Safety
Air sonar systems support gunshot, explosion and abnormal sound localization in urban areas.
Temporary Events
Portable acoustic systems support event protection, field deployment and mobile emergency response.
Acoustic Security & Sonar FAQ
Common questions about acoustic defender systems, air sonar, gunshot localization and security sound sensing.
What is an acoustic defender system?
An acoustic defender system uses buried or distributed acoustic and vibration sensors to detect events such as footsteps, vehicles, digging or intrusion activity along protected areas.
How does air sonar locate gunshots or explosions?
Air sonar uses a microphone array to capture sound arrival time differences. The system estimates the direction of the acoustic event and can support camera linkage for visual confirmation.
When should I use HZ-DA-200?
HZ-DA-200 is suitable for buried perimeter and border-style security applications where hidden detection, outdoor reliability and vibration-based intrusion awareness are required.
When should I use HZ-SN-16?
HZ-SN-16 is suitable for air acoustic localization scenarios such as gunshot detection, explosion localization, urban safety monitoring and CCTV linkage workflows.
Can acoustic security systems connect with camera platforms?
Yes. Depending on the project architecture, acoustic event outputs can be integrated with CCTV, PTZ cameras, security platforms or command systems to support faster verification.
